Abstract

The main objective of this study is to design and analyze the important components of pressure vessel according to the internal design pressure and temperature by using finite element method. A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from ambient pressure. They have been widely used in a variety of applications such as, in chemical industries, in thermal and nuclear power plants, in food industries, and aircraft industry. Therefore, the pressure vessels are to be designed carefully to avoid the failures which are mostly stress dependent. The requirements of stress analysis are needed to avoid the failure and the fatal accidents of pressure vessel. In this study, the important components of pressure vessel such as a blind flange, a shell flange, some eye bolts, a drain pipe, a drain pipe flange, and some junction areas of pressure vessel were specifically designed with reliable materials in accordance with ASME Code. The finite element modeling, the evaluation of equivalent stress, and the stress classification lines (SCLs) for specified points were performed using a Midas NFX program based on the finite element method (FEM). The stress analysis for the design condition involving internal pressure and thermal load has been evaluated in accordance with ASME boiler and pressure vessel code. The conclusion is that the analysis results for the normal operating condition satisfied allowable limits. Therefore, the current design of the pressure vessel has enough strength under the design load conditions.
